An interpreter compiles and executes each line of a program one at a time
with no compile cache. Perl is more like Java in that it precompiles all
the program into a "byte code" version which is then executed. A line in a
Perl script is, in theory, only 'compiled' once - there are exceptions to
this. However, this is why mod_perl accelerates scripts so much (1%-40000%
improvement) - it caches the 'compile cache'.
